Why Do Two 2020 Hyundai Palisades Take Different Windshields?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Because one 2020 Palisade has a head-up display and rain-sensing wipers and the other does not. Both carry a camera with a static calibration, acoustic glass and a humidity sensor, but those two extras make it a separate part that also needs a rain sensor pad. Head-up display glass cannot be substituted.
The two 2020 Palisade windshields
FW05241GTYN
- Camera with a static calibration
- Acoustic glass
- Humidity sensor
- No head-up display, no rain-sensing wipers
FW05242GTYN
- Camera with a static calibration
- Acoustic glass
- Humidity sensor
- Head-up display and rain-sensing wipers
- Needs a rain sensor pad or optical gel
The head-up display is the one difference that changes the part. Glass with a wedge interlayer cannot be substituted for ordinary glass, so the VIN settles it before anything is ordered.
Why the head-up display changes the glass
A head-up display projects speed and directions onto the windshield so they appear to float above the hood. For this to work without a doubled image, the glass uses an interlayer that is wedge-shaped, thicker at the top than the bottom, so the projected light reaches the driver as a single picture. Ordinary laminated glass has a flat interlayer, and fitting it in a head-up display Palisade leaves the driver looking at two overlapping images permanently.
Nothing in a calibration routine corrects it, since the fault lives in the glass rather than the camera aim. The fix is to refit the windshield using the proper wedge-interlayer part, which is why the head-up display is checked against the VIN before any glass is ordered. The second Palisade part also adds rain-sensing wipers, which means a rain sensor pad or optical gel has to go in with the glass, an accessory the first part does not list.
Both parts share a camera with a static calibration, which is shop work: the vehicle stationary, targets at measured distances on a level floor, controlled lighting. That part of the job happens at a shop rather than on a driveway, and we say so before you book rather than after a technician arrives.
Signs the wrong Palisade glass went in
- A doubled picture in the head-up display
- Ordinary glass without the wedge interlayer was fitted. The projection doubles, and no calibration corrects it. The glass has to be replaced with the correct part.
- A quote that never mentioned the head-up display
- The shop is quoting from the model name rather than the VIN. Two 2020 Palisades take different glass, and only the VIN confirms which one yours is.
- Automatic wipers sweep a dry screen
- The rain sensor pad or optical gel was not fitted with the glass on the head-up display part. The sensor reads the new glass as wet and triggers the wipers.
Questions about the Hyundai Palisade windshield
How do I know which 2020 Palisade windshield my car has?
Only the VIN tells you. The two parts differ by the head-up display and rain-sensing wipers, and neither shows on the outside. We pull the exact part number off the VIN before the quote is built. See our Hyundai windshield page.
Can a Palisade with a head-up display use ordinary glass?
No. Head-up display glass uses a wedge-shaped interlayer so the projected image is not doubled. Ordinary glass leaves the driver with two overlapping images permanently, and no calibration fixes it. The right wedge-interlayer part is pinned down through the VIN.
What does a Hyundai Palisade windshield replacement cost?
A windshield replacement runs $200 to $500+ out of pocket before tax, set by which part your Palisade was built with. Both Palisade parts carry a camera, so the static calibration is folded into the same quote as the glass.
